If you are looking for one throat to choke for a virtualized x86 server stack, the right one is tough to find. But Oracle wants you to wrap your hands around Larry Ellison's neck, and is betting that its new Virtual Compute Appliance works so well and is such a good bargain that you won't squeeze.

Larry's expensive walled garden or real choice.

So you can have Oracle's servers (which no-one buys) and Oracle's kludge of bought, copied and "free" expensive software (the majority of which no-one buys), a lot of which they don't even have the original developers still employed at Oracle. Or you can go to hp, Fujitsu or IBM and they will do you a much better x64 server range, storage, switches and they'll offer a complete stack from Microsoft, VMware or Citrix, all with support that actually knows how it works, and build just about any software stack you want on top. And they can also do RHEL or SuSE options with real support for even more choice. Yeah, so what was Larry's point?
